研究了一种新的反相微乳法合成乳酸脱氢酶纳米血小板。该方法采用具有多种功能的油相、碱和表面活性剂的油胺。制备的MgAl-LDH纳米血小板平均直径（μ）分别为49.2、64.0和75.4 nm，标准差（σ）分别为15.0、17.2和16.0 nm。原子力显微镜研究表明，纳米血小板平均分别由14层、20层和35层组成。所观察到的LDH纳米颗粒的平均直径和厚度与油胺-水比呈线性关系。
A novel reverse microemulsion approach for the synthesis of LDH nanoplatelets has been developed. The method employs oleylamine which performs multiple functions, acting as the oil phase, base and the surfactant. MgAl-LDH nanoplatelets have been prepared with mean diameters (μ) of 49.2, 64.0 and 75.4 nm with standard deviations (σ) of 15.0, 17.2, and 16.0 nm respectively. AFM studies show that on average the nanoplatelets comprise of 14, 20 and 35 layers respectively. The observed mean diameter and thickness of the isolated LDH nanoparticles is linearly dependent on the oleylamine–water ratio.
